Abstract: 900,480. Cash registers. BELL PUNCH CO. Ltd. March 10,1959 [Dec.11, 1957], No. 38551/57. Class 106 (1). A key-responsive cash register has a visible primary register into which amounts set on the keyboard are entered, a secondary register to which amounts may be transferred from the primary register so as to accumulate a grand total of these amounts and an indicating arrangement by which amounts entered into the primary register may be further displayed. The cash register described is a modification of the full-keyboard key-responsive calculating machine described in Specification 720,088 which has a primary register in front of the keyboard and a secondary register at the rear to which totals may be transferred from the primary register. In the present machine, the toothed segments 70, which in a transfer operation are differentially set under the control of stop plates 11 positioned by the primary register and are engaged with pinions 10 of the secondary register during restoration, also engage pinions 50 driving, through pinions 51, switch wiper arms 54. At the beginning of a transfer operation, pawls 60 are disengaged from the pinions 51 which are then restored clockwise to zero positions by springs. The pawls are reengaged during the restoration of the segments 70 and ratchet over the teeth of the pinions 51. The switches are connected with indicating tubes 73 each having ten cathodes arranged to indicate the digits 0-9. One such tube is provided for each of the farthings, unit-shillings, ten-shillings and the various pounds denominations whereas two are provided for the pence order. The indicating-tube circuit is broken during a total-transfer operation by contacts controlled by a portion of the total-transfer mechanism. In a modification, Fig. 3, the secondary register segments 100 are coupled by links with arms 101 coupled by pawls 108 to segments 104 which are thus differentially positioned to place bridging contacts 135 across number contacts 128 and arcuate contacts 129. Immediately prior to the setting movement, the segments 104 are zeroized by springs 105 being released for this purpose by the pawls 108 which are raised by slides 116 actuated by a bail 137 rocked by the restoring bail 145. The contacts are connected to number contacts of an indicating device similar to that described in Specification 868,753 and having for each order a number wheel 147 driven by its shaft 149 and arranged to bridge successive number contacts and a common contact. When the contact marked by the associated bridging contact 135 is reached, a solenoid 155 is energized to arrest the wheel 147 in a corresponding position. On operation of the total transfer lever 200, Fig. 5, a latch 220 is raised to release a cash drawer 260. The latch 220 is held by a pawl 222. When the drawer is pushed back, a cam 268 rocks a lever 235 and, through a spring 244, a lever 234 is also rocked. This lever actuates a link 233, to rock the lever 230 which as described in Specification 720,088 causes the primary register to be zeroized. As the drawer reaches its inner position, a finger 265 disengages the pawl 222 to allow the latch 220 to re-engage. Totals may be transferred subtractively to the secondary register as described in Specification 720,088,but this mechanism is normally locked. Specifications 868,756,868,757,868,758, 868,759, 868,760 and 868,761 also are referred to.
